Pushing for elfutils to become more like BFD is not likely to gain
many fans :)

We drop the patch for now. Yes, dwfl_module_addrname/sym () doesn't work
as expected for ppc64. You convinced me that we don't want to introduce
new functions for this just for ppc64 because that would be too inconvenient
for the users. I explained a couple of times now how dwfl_module_addrname/sym
can be made to work for ppc64. But it seems you cannot/don't want to do
that. So we are now just stuck, unless someone else fixes it.

I am not going to endlessly discuss this over and over again with you.
There is more important stuff to concentrate on for now.
